Greater Chicagoland Air Quality Solutions
Greater Chicagoland Air Quality Solutions
Modern home construction creates an airtight seal that improves energy efficiency but traps dust, allergens, and moisture inside. Without proper ventilation, indoor air quality stagnates. This leads to issues like dry winter skin, heavy summer humidity, and trapped pollutants. Our indoor air quality services restore balance by managing moisture levels and removing airborne dust throughout your home.
Unlike portable units that treat one room at a time, whole-house systems connect directly to your heating and cooling equipment and ductwork. This ensures all circulating air is cleaned and conditioned. Our technicians test your air, inspect your existing system, and install solutions designed specifically for Illinois weather.
Since 1965, AA Service Co. has delivered dependable air quality and HVAC solutions to homeowners across Greater Chicagoland and the North Shore.

Comprehensive Care
Reliable Indoor Air Quality Services and Equipment
Whole-house systems connect to your ductwork to treat every room simultaneously, running quietly with minimal upkeep.
Whole-Home Air Purifiers & Cleaners
Winter heating systems dry out indoor air, causing static shocks, cracked woodwork, and dry skin. ASHRAE guidelines suggest maintaining indoor relative humidity between 30% and 50%. Whole-house humidifiers add balanced moisture directly into your supply ducts.
Midwest summers bring high humidity that creates discomfort and encourages mold growth. EPA guidelines recommend keeping indoor humidity below 50%. Central dehumidifiers remove excess moisture daily, reducing the workload on your central A/C.
Properly balanced humidity is key to comfort and health. We install and service whole-home systems that automatically control your home’s humidity levels, helping to reduce dry skin, protect wood furnishings, and prevent mold growth.
Cracks in return ducts pull dirty air from attics, basements, and crawl spaces. Professional duct sealing closes these leaks to keep your air clean and reduce energy waste.
If your home suffers from lingering odors or rapid dust buildup, an air quality assessment identifies ventilation defects, duct leaks, and moisture problems.

Frequently Asked Questions
Answers About Indoor Air Quality Services
How do I know if my home has poor indoor air quality?
Common signs include rapid dust buildup, static electricity, stale odors, and allergy flare-ups. Sticky summer rooms and winter window condensation also signal humidity issues.
What is the ideal indoor humidity level for Midwest homes?
Both ASHRAE and the EPA recommend indoor relative humidity between 30% and 50%. During cold Chicago winters, keeping levels around 30% to 35% prevents window condensation and protects wood floors. In summer, keeping humidity under 50% prevents mold growth.
Can air quality equipment work with my existing HVAC system?
Yes. Whole-house humidifiers, dehumidifiers, and media air cleaners connect with standard furnaces, heat pumps, and air handlers.
How often do filters and humidifier pads need replacement?
Deep-pleated media air filters typically last 6 to 12 months. Humidifier evaporator pads need replacement once per year before winter heating begins.
What are the trade-offs between whole-house systems and portable units?
Portable units treat single rooms and require manual maintenance. Whole-house systems connect to your ductwork, manage your entire living space automatically, and operate out of sight.
